It wasn't really hard runnin a mob family in the 50s and 60s . The Feds didn't even pursue the mob like they do today or from the 80s on . There was no Rico , wiretaps and stiff sentences for drug dealing so that meant fewer rats . To me it's 50 times harder running a mob family from the 80s to the present , u can't possibly compare gambino and accardo to bosses like massino , gotti and gigante , they had it a lot tougher. Wen the Feds made a concerted effort to target the mob they were successful . Guys like persico, rastelli, corallo and Salerno were sent to prison straight away . No doubt if the Feds made the same effort in the 50s bonanno , lucchese gambino and accardo would have gone the same way
